EDMUND J. CRIDGE, OF TROY, NEW YORK.

COOKING-STOVE.

Specification forming part of Letters Patent No. 90,342, dated May 25, 1869.

To all whom it may concern:

Be it known that I, EDMUND J. CRLDGE, of the city of Troy, in the county of Rensselacr and State of New York, have invented a new and useful Improvement in Cooking-Stoves; and I do hereby declare that the following is a full, Clrfll, and enact description thereof, ref erence being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a perspective view of a cookingstove having my improvement applied to it, as the stove would appear by making a longitudinal section through its center in a vertical plane and removing one half. Fig. 2 is a longitudinal section taken through the center of the stove in a vertical plane. Fig. 3 is a top view of the stove with the rear portion of its top plate broken away and the water-reservoir removed. Fig. at is a perspective view of the vertical flue-plates, adapted for supporting the water-reservoir. Figs. 5 and 6 are modifications of the arrangement shown in Figs. 1 and 2.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to provide for arranging a water-reservoir within a fluespace formed by a rear extension of the body of a cooking-stove, so that the vertical flueplates shall extend beneath and up the front and rear sides of such reservoir and afford supports therefor, and also admit the removal of the reservoir at pleasure.

I am aware that cooking-stoves have been constructed with rear extensions, constituting parts of such stoves, adapted for receiving, in a permanent manner, within them water-reservoirs, and that under such arrangement provision was made for direct and indirect drafts, the direct draft passing through a channel or fine formed in the top of the water-reservoir, and the indirect draft passing around the oven and beneath the said reservoir thronghsheet fines. Such an arrangement will be found in Letters Patent numbered, respectively, 83,085 and 83,086.

In these stoves just referred to the waterreservoirs are permanent fixtures, and are constructed within the flue-spaces of the stoves in such manner as to form part of the direct fines leading to the escape-pipes, and part of the indirect fines leading around the ovens. Being permanent fixtures, the reservoirs cannot be removed from their places for repairing or cleaning, nor are they afforded the firm supports which are required to render them substantial.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

The body of the cooking-stove may be constructed of the well-known rectangular form, with an extension, N, in rear of the oven, for receiving a part or the whole of a water-reservoir.

A is the fire-chamber, B the ash-pit, and O the interposed grate, which are arranged in the frontpart of the stove, in front of the oven D.

There is a horizontal sheet-flue, a, leading from the fire-chamberA, between the top plate, A, of the stove and the top plate of the oven,

to the rear of the oven, and communicating with flues which extend behind and beneath the oven, and beneath and behind the waterreservoir J, as shown in Figs. 1 and 2. These flues, which are back of and beneath the oven and water reservoirs, are formed by means of vertical plates G G, constructed as clearly shown in Fig. 4, and arranged within the flue-spaces so as to form when the damper b is closed, as shown in Figs. 1, 2, and 3, the indirect side fines, a a, and the intermediate flues a a a, leading from the sheet-flue a down the rear end of the oven, beneath its bottom, and thence to the escape-pipe g, which is through the top plate of the stove.

The flue-plates G G are constructed with offsets upon their vertical limbs, which are adapted to serve as brackets and afford supports for the water-reservoir J, the bottom J of which will be received and supported by the vertical and horizontal edges of said platesGG. These offsets of the flue-plates not only serve as bearin gs for the water reservoir, but they also serve to divide the chamber beneath and at the back of the said reservoir into fines a, corresponding to the side and intermediate fines at the back and bottom of the oven D.

The reservoirs shown in Figs. 1 and 2 consist of an external portion, J, provided with a cover, j, and rising any required height above the top plate of the stove, and an internal por tion, J extending below the top plate of the stove, and impinging upon the edgesi of the bracketextensio'ns ofthe flue-plates G G, as shown in Fig. 2.

When the damper b is open the products of combustion will pass directly to the pipe 9, and in doingso will impinge against the front portion, J, of the water-reservoir. When this damper is shut the products will take the course indicated by the arrows in Figs. 1, 2,, and 3, passing down the side flues, a a, thence toward the front of the stove, beneath the oven, thence return, by way of the intermediate flues a a to the escape-pipe g; and in thus passing about the oven the products will circulate in the spaces beneath, and up the back side of the water-reservoir, and will be retained in these spaces as long as the products will communicate heat to the reservoir.

In Fig. 5 the same arrangement is shown, with this exception, that the reservoir is contained wholly within the extension at the back of the stove, and its cover j is in the plane, or nearly so, with the top plate of the stove.

In Fig. 6 the arrangement difi'ers somewhat from that above described. In this form of stove the escape-pipe is located in rear of the water-reservoir, so that whether damper b is open, for obtaining a direct draft, or shut, for obtaining an indirect draft, the products will in both cases pass beneath the water-reservoir, through their respective flues, formed by plates G G, on their way to the escape-pipe g. Under this latter arrangement the Water-reservoir may be wholly or only partially arranged within the flue-space.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

A removable water-reservoir which is inclosed within a flue-chamber formed between the back wall of the stove and the back wall of the oven, and which is supported in such a EDMUND J CRIDGE.
